Date question

[Porl123]

I have a php script that allows the user to enter a day, month and year, for example 10/10/2001. What I'm trying to do is find out how many years that date is from now, taking into account the days and months along with the years. So say I have the variables:

 

<?php

$day = 10;

$month = 10;

$year = 2001;

?>

 

I've been thinking about this for a while now and I can't really think of how I would do it. If anyone can give me a hand I'd really appreciate it. (: Thanks!

first you find the difference between the two years and then you should have two if statements checking the following

 

1. is the given month higher than the current month

2. is the given month equal to the current month, if so, is the given day higher than the current day?

 

if any of those are true you should substract 1 from the year difference

 

NOTE: If you don't check if the year is zero then you will end up with -1

Thanks for the reply. Does this take leap years into account, btw?

[Porl123]

Or rather the different lengths of each month?

[ZacTopher]

that checks only the day, month and year against the current date..

Ah, I've finally got my head around it. Thanks for the help Zac
